Balcony Defect Audits:
Stop Efflorescence & Leaks.
Balcony waterproofing failures, inadequate drainage falls, and core-drilled balustrades represent the single largest liability for strata owners and builders in Australia. We provide forensic non-destructive investigations, screed moisture testing, and Scott Schedule reports.
The Top 3 Balcony Failures in Australia
Ignoring balcony leaks results in structural concrete spalling (cancer), rot of timber floor joists, and catastrophic liability if balustrades detach.
Efflorescence & Tile Debonding
Water trapped under tiles in the sand-cement screed dissolves calcium hydroxide, forcing white calcified stalactites and salts through grout joints, lifting tiles off the slab.
Core-Drilled Balustrade Penetrations
Balustrade contractors core-drill through completed waterproofing membranes into the structural slab without installing specialized sealing collars, funneling water into units below.
Inadequate Fall & Doorway Overflows
Balconies built with less than the mandatory 1:100 slope to drains (or 1:80 for screeds) trap ponding water that breaches sliding door tracks during severe rainstorms.
Why "Tile-Over" Clear Sealants Always Fail
Contractors frequently sell cheap "clear waterproofing sealants" painted over existing tiles. Within 6 to 12 months, UV degradation, thermal movement, and moisture trapped beneath the tiles cause the sealer to turn milky white and peel away. Our reports provide the engineering specifications for permanent sub-tile drainage remediation.
